From my first conversation with Dan to my last conversation with tech support. Is has been a great experience. I have it installed and working better than expected.
Great battery to pair with the eg4-6000xp inverter. This is the 2nd battery now I've added to my system bumping capacity to 560ah 28.6kwh. These batteries are not cheap though so ROI will take a while. The guys at Sudbury Solar Solutions are great. They delivered and brought the battery into the home and set it in the spot I needed. (battery weighs ~300lbs). Would not hesitate to buy from Sudbury Solar Solutions again. Top notch.
